Answer:

x = 3

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, that is

DE = AB , substitute values

6x - 7 = 11 ( add 7 to both sides )

6x = 18 ( divide both sides by 6 )

x = 3

Answer this question

Murljashka [212]

Answer:

a = p * q

b = p * s + q * r

c = r * s

Step-by-step explanation:

In the trinomial ax² + bx + c

a is the coefficient of x²

b is the coefficient of x

c is the numerical term

∵ The trinomial is ax² + bx + c

∵ Its factors are (px + r) and (qx + s)

∴ ax² + bx + c = (px + r)(qx + s)

∵ (px + r)(qx + s) = (px)(qx) + (px)(s) + r(qx) + (r)(s)

∴ (px + r)(qx + s) = pqx² + (psx + qrx) + rs

∴ ax² + bx + c = pqx² + (ps + qr)x + rs

→ By comparing the two sides

∵ ax² = pqx² ⇒ divide both sides by x²

∴ a = pq

∵ bx = (ps + qr)x ⇒ Divide both sides by x

∴ b = ps + qr

∴ c = rs

∴ a = p * q

∴ b = p * s + q * r

∴ c = r * s

How many pounds of a 4% solution of borax must be added to 24 pounds of a

Marrrta [24]

Answer:

8 pounds of 4% solution of borax

Step-by-step explanation:

Let x be the 4% solution

24 pounds of 12% solution

obtain a 10% solution of borax that is (x+24) pounds

4% is 0.04 and 12% is 0.12 , 10% is 0.1

$0.04x+24(.12)=0.1(x+24)$

solve the equation for x

$0.04x+24(.12)=0.1(x+24)\\0.04x+2.88= 0.1x+2.4\\2.88= 0.06x+2.4\\0.48=0.06x\\x=8$

so 8 pounds of 4% solution of borax

Which function best fits the following points?

Rudik [331]

Answer:

Correct answer is choice B.

Step-by-step explanation:

We have been given a graph and 4 different choices.

Now we need to determine about which of the given functions best fits the points in the graph.

From graph we can clearly see that points are going upward very fast as compared to x when x-value increases.

That happens in exponential type function which is usually written in form of

$y=ab^x$

Choice B looks similar to that.

hence correct answer is choice B.
